[amsat-bb] QSL CARD EXCHANGE

Greetings,

I have a question about exchanging QSL cards. When the last time the ISS xband repeater was up I made seven contacts. I was very excited because this was the first time I was able to work satellites. Very anxious, I sent out seven QSL cards. Waiting to get some back. I received only one. My questions is, is there a protocol for sending and receiving QSL cards for satellite work? When I get better, I would like to try for VUCC... Thanks in advance. 73, Stuart W8STU EN91
